DEHN protects with BLITZDUCTOR® XT

BLITZDUCTOR® XT with LifeCheck® –Protection and maximum availability

2

DEHN protectsProtection of workers and material assets is of utmost impor-tance to us. To this end, our solutions combine knowledge of the specific industry with long-standing technical experience in surge protection, lightning protection and safety equip-ment. Our economically and technically sound lightning and surge protection concepts ensure system availability and protect your investments and yields in the long term.

BLITZDUCTOR XT combined arresters with integrated Life-Check are a perfect example of the efficiency, quality and safety of our products.

BLITZDUCTOR® XT – a multi-purpose combined arrester

Compact in design, the BLITZDUCTOR XT base part and protection modules perfectly complement each other for DIN rail mounting. The universal base part minimises sto-rage requirements and eases prewiring and maintenance operations.

BLITZDUCTOR® XT is reliable

BLITZDUCTOR XT ensures maximum system availability since the modules can be replaced without signal interrup-tion. All protection elements are integrated in the module, thus facilitating replacement and maintenance.

BLITZDUCTOR® XT is robust

Thanks to its snap-in mechanism, the arrester provides pro-tection against vibration effects and shock up to a 30-fold acceleration of gravity. The function-optimised design allows to replace the module without problems.

BLITZDUCTOR® XT is intelligent

The unique RFID-based LifeCheck technology allows fast and easy testing of arresters without removing the module from the system circuit. LifeCheck immediately indicates imminent electrical or thermal overload of the components. The test devices of the DEHNrecord family allow to con-tactlessly detect potentially pre-damaged arrester without interfering with the signal circuit. The condition monitoring module permanently monitors the condition of the arrester, thus ensuring maximum availability.

BLITZDUCTOR® XT is versatile

Arresters of the BLITZDUCTOR XT family were tested in external test laboratories according to application and country-specific requirements and international standards. Their suitability for different fields of application was also tested, for example the use of BLITZDUCTOR XT Ex (i) in potentially explosive atmospheres.

Space in switchgear cabinets is limited. For this reason, the base part and the protection modules are compact in design and thus ideal for DIN rail mounting. Since the base part can be used for every type of module, storage require-ments are minimised.

Over a width of only 12 mm, up to four single lines or two pairs can be connected on two levels. For DIN rail moun-ting purposes, lines of a pair belonging to each other are connected on top of one another.

The BLITZDUCTOR XT base part is a four-pole universal feed-through terminal for insertion of the protection module without signal interruption. Since no components of the protective circuit are integrated in the base part, maintenance operation is only required for the protection modules. This allows modules to be replaced without inter-rupting the signal circuit.

The function-optimised arrester design allows to safely plug the protection module into the base part and to remove it without problems. The module is secured in the base part by snapping it in (audible click).

This snap-in mechanism ensures safe operation even in case of vibration effects and shock up to a 30-fold accele-ration of gravity.

A module release spring and laminated spring contacts in the base part allow to easily remove the module by pres-sing the grey module release button. A mechanical reverse polarity protection ensures that the module is installed in the correct position.

BLITZDUCTOR XT with LifeCheck uses RFID technology for monitoring the protective circuit and for communication. All arrester elements of BLITZDUCTOR XT are monitored in the protection module. Thus, imminent electrical or thermal overload of the components is reliably detected before the arrester fails and the availability of the system to be protected is limited.

A monitoring circuit with a transponder in the arrester permanently monitors the protective circuit for pre-damage caused by thermal overheating or impulse currents. The RFID reader allows to read out information within a matter of seconds without removing the arrester. Thus, tests can be carried out without downtime.

The DEHNrecord LC tester allows to quickly and contact-lessly carry out tests without downtime. It indicates the status of the arrester and the date of the last test. In case of pre-damage, preventive replacement of the arrester ensures system availability.

Robust: Snap-in mechanism makes the arrester vibration and shock-resistant

Intelligent: LifeCheck® detects pre-damaged arresters

Lightning strikes and surges may bring systems to a stand-still. In case of airport or railway signalling systems, such a standstill represents a substantial hazard to human life. Safety is therefore a key reason for deciding in favour of condition monitoring. Another reason is to increase pro-ductivity through maximum system availability. The lower the downtime, the higher is the production output.

TheDEHNrecordSCM/MCMXTmonitoringdevicesmakecondition monitoring easy. They monitor up to ten protec-tion modules, identify pre-damage and show the module affected. Pre-damaged arresters can be replaced in time without signal interruption and affecting the operation of the system thanks to the make-before-break switch contacts. Thus, the system is available at any time and protected against interference.

In case of imminent arrester overload, the three-coloured LED indicates this fault condition and transmits it via the remotesignallingcontact.Malfunctionoftheconditionmonitoring module, for example due to a power failure, is also indicated.

Condition monitoring in-creases safety and system availability

DEHNrecord MCM XT monitors up to ten protection modules

Data networks and measuring and control systems are equipped with numerous interfaces that place different re-quirements on the performance of protection components. Besides protecting the interface against lightning strikes and surges, the arresters also have to transmit system-relevant signal parameters.The BLITZDUCTOR XT family easily masters this task: The modules are adapted to the different interfaces, thus provi-ding protection and availability for the signal circuits and system components.

... level-crossing protection systems

Level crossings are critical points that must be reliably protected. Completely electronic level crossing protection systems are sensitive to surges and the peripheral elements are often far away from the signal distributor.

Together with industrial companies and German Federal Railways, DEHN developed a lightning and surge protection system for railway signalling equipment. This system includes BLITZDUCTORBXTML4BE36combinedarrestersforinfor-mationtechnologysystems,theDEHNrecordMCMXTcon-dition monitoring system and type 2 DEHNguard arresters for power supply systems. These surge protective devices can be flexiblyusedaccordingtothephysicalsystemstructure.Thisprotection concept was approved by the German Federal Railway Authority.

... wind turbines

Due to their exposed location and height, wind turbines are prone to lightning strikes which may damage the rotor blades or electrical and electronic components. The con-sequences are downtime and high repair costs. To ensure uninterrupted operation and amortisation of the high investment costs, wind turbines must be integrated in a lightning and surge protection concept.

Leading wind turbine manufacturers rely on lightning and surge protection equipment from DEHN, a market leader with long-standing experience and international presence. DEHN not only offers surge protective devices, but also ex-ternal lightning protection systems including air-termination systems, down conductors and earth-termination systems. New customised solutions are also developed. The protec-tion of pitch controls and data systems by BLITZDUCTOR XT combined arresters, e.g. for measuring the wind speed and direction, is a good example.

DEHN protects investments in wind turbines.

... hazard warning systems

If lightning strikes or surges destroy hazard warning systems, safety-relevant functions of the system may fail. Emergency call or fire alarm systems are longer available, representing a substantial hazard to human life. Surges also frequently cause false alarms and thus high costs. For these reasons, it is essential to integrate hazard warning systems in a lightning and surge protection concept.

Hazard warning system manufacturers have tested and approved BLITZDUCTOR XT combined arresters. These arrestersarealsoVdS-certified.

DEHN protects human life in dangerous situations.
